Hello, I am 39 years old. I am noticing a lump in my thyroid since 2 weeks. Could it be a cancer? Because it's growing gradually. My symptoms include enlarged thyroid gland, vision problems and eye irritation. Heat sensitivity (trouble dealing with heat) is also there. There is decrease in appetite. Please suggest what should we do?

@palak A thyroid nodule is an unusual growth (lump) of thyroid cells in the thyroid gland. The thyroid is part of the endocrine system, which is made up of glands that secrete various hormones into the bloodstream. The thyroid is a butterfly-shaped organ (or gland) that is located on the front of the neck, just under the Adam's apple (larynx). The thyroid gland, which is made up of the right and left lobes connected to the isthmus (or “bridge), produces and releases thyroid hormones. Thyroid hormones control functions such as body temperature, digestion and heart functions. Treatment depends on the type of thyroid nodule. Treatment options include: No treatment/"watchful waiting." If the nodules are not cancerous, you and your doctor may decide that you don’t need to be treated at this time. You will see your doctor on a regular basis so he or she can watch for any changes in the nodules. Radioactive iodine. Your doctor may use radioactive iodine to treat hyperfunctioning thyroid nodules and goiters with several nodules. The radioactive iodine is absorbed into the thyroid gland, causing the nodules to shrink. Pregnant women and women trying to become pregnant should not have this treatment.
